[Tex/LaTex] Arrow with text above

arrowssymbols

I am drawing an arrow using the following command:
$ \xleftarrow{\mbox{\tiny{BCast}}} $‎.
I have tested the command in two different environments:

  1. TeXShop (MacOS, uses TeX Live) outputs an arrow with the problem stated in the second item.
  2. TeXmaker (Windows, uses MiKTeX) in a bidirectional environment (for writing Farsi) outputs the correct arrow with "Bcast" above it but the arrow seems to have splitted areas that are connected using dots.

Am I doing it wrong?
Edit: this is the "preview" rendering of the file under zoom of 1000x.

I guess that the arrow only seems "to have splitted areas that are connected using dots". This comes from the definition of the extendible arrows. It's a previewer problem; in print you shouldn't see it. To check if it is a previewer problem, zoom in really deep, say with a magnification of 3000%, and see if it looks OK then.
